i wanna start by saying i searched all over and saw too many different "possible solutions/problems" for the buzzing, metallic noise i get from the art pipes

i just installed them on my 08 Z and from 1k-2.5k rpm i get this disgustingly loud rattling from just under my driver side floor board. i can even feel the vibraation on my feet.

this is aside from the normal rasp that test pipes bring. i have everthing else stock on my exhaust. again, i really believe this isnt rasp..this is a vibrating between two metals kind of noise..

what is this and how can i fix this? is this the heat shield under the driver side pipe? during installation, it was touching it but we pushed it away with a screwdriver so it didnt touch. also the small bolt there is cut..

thanks guys..

 

and i know this isnt rasp cause i get rasp all the way through my powerband but this is something i would heaar on the low end just driving around town/in traffic but its LOUD

 

it is prob the heat shield, i had to bend mine a couple times in a couple places...

You need to cut some length off of the driver side stud hanging directly above the resonance chamber of the ART pipe. Climb underneath; you should see it.

Edit: Just noticed you said you already cut it. Not too sure what it could be. Can you record a video?

 

 

he said he cut the bolt in the original post

 

Whoops, missed that...

Like trav said most likely keep smashing the heat shield.

 

100% it's your driver's side heat shield.
